“Could the lightning have made the bell ring? You know it’s an electric bell,” suggested Mrs. Bobbsey. “Bert said it might do it.”

“Perhaps,” admitted her husband. “I’ll take a look at the bell in the morning. It may be that it is so sensitive that the least jar of thunder will make it ring.”

“Did you save the lumber?” his wife asked.

“All but a few planks that got away from us. The river and lake are very high. We’ve had a lot of rain this spring. Now I think I’ll eat something and go to bed. Looks as if the rain would keep up into May.”

“That’s right,” agreed the twins’ mother. “To-morrow is the first of May, isn’t it?”

Her husband nodded as he sat down to a lunch she made ready for him.

It was still raining when Mr. and Mrs. Bobbsey went to bed. But it stopped some time during the night, and when the Bobbsey twins awakened in the morning the sun was shining bright and warm.

“Hurray!” cried Bert, as he looked from his window. “It’s cleared off!”

“And there’s a big lake in the back lot!” shouted Freddie. “I can see it from my window.”

“We’ll sail boats there after school,” decided Bert, as he began to dress.
